[0041] The technical solutions in some embodiments of the present application will be described below in conjunction with the drawings in some embodiments of the present application.

[0042] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0043] The main function of the guide rail in the machine tool is to support the moving parts and guide them. It is a key component that affects the machining accuracy of the machine tool. Therefore, in the process of machine tool assembly, the straightness measurement of the guide rail is very important.

[0044] For the straightness measurement of machine tool guide rails, generally, the more measured data, the higher the accuracy of the measurement results. However, too many measurements will not only increase the workload of the measurement personnel, but also the measurement time is too long, the detection environment may change, and the accuracy of the measurement results may become lower. How to improve the efficiency and accuracy of the straightness measurement of the guide rail is a problem that needs to be solved urgently. In view of this, some embodiments of the present application provide a guide rail straightness detection method, which includes sending transmission data from a first detection point on the guide rail to be detected based on a transmitter, and obtaining received data of a second detection point on the guide rail to be detected; the first detection point and the second detection point are different detection points on the guide rail to be detected; according to a preset fitting algorithm, the received data is fitted to obtain the straightness of the guide rail to be detected. In the embodiment of the present application, multiple received data can be obtained in one measurement process, and multiple received data are used for data fitting to obtain the straightness to be detected, thereby improving the detection efficiency and accuracy.

[0045] like Figure 1 As shown, an embodiment of the present application provides a guide rail straightness detection method, the method comprising:

[0046] S101, based on the transmitter sending transmission data from the first detection point on the guide rail to be detected, obtaining reception data from the second detection point on the guide rail to be detected; the first detection point and the second detection point are different detection points on the guide rail to be detected;

[0047] Specifically, different detection points are set on the guide rail, and the number of detection points can be one or more. A transmitter and a receiver of a laser detector are set at each detection point. If a transmitter is set at one detection point to send out transmission data, the receivers at other detection points receive reception data corresponding to the transmission data.

[0048] Exemplarily, if five detection points are set on the guide rail, transmission data is sent out at the first detection point, and data is received at the other second, third, fourth and fifth detection points.

[0049] S102. Perform data fitting on the received data according to a preset fitting algorithm to obtain the straightness of the guide rail to be tested.

[0050] Specifically, the terminal device uses a preset fitting algorithm to perform data fitting on the received data to obtain the straightness of the guide rail to be detected.

[0051] Exemplarily, the least square method is used to fit the data, as follows:

[0052] The least squares method is used to solve the problem of curve fitting. Its basic idea is:

[0053]

[0054] in, is a set of linearly independent functions selected in advance, a k is the unknown coefficient, k=1, 2,…, m, and the fitting criterion is to minimize the sum of the squares of the distances between yi and f(x).

[0055] Some embodiments of the present application can obtain multiple received data in one measurement process, use the multiple received data to perform data fitting, obtain the straightness to be detected, and improve the detection efficiency and accuracy.

[0056] Another embodiment of the present application further supplements the guide rail straightness detection method provided in the above embodiment.

[0057] Optionally, based on the transmitter sending transmission data from the first detection point on the guide rail to be detected, obtaining reception data from the second detection point on the guide rail to be detected includes:

[0058] Based on the transmission data sent by the transmitter at any first detection point, respectively obtain the reception data of multiple second detection points;

[0059] Based on the received data, the height difference between two adjacent detection points is calculated abnormally.

[0060] Some embodiments of the present application obtain a large amount of received data through one measurement, which can greatly reduce the number of measurements and improve the measurement efficiency.

[0061] Optionally, data fitting is performed on the received data according to a preset fitting algorithm to obtain the straightness of the guide rail to be detected, including:

[0062] The least square method is used to fit the height difference between two adjacent detection points to obtain the straightness of the guide rail to be detected.

[0063] Some embodiments of the present application use a preset fitting algorithm to perform data fitting on the height difference between two adjacent detection points to obtain the straightness of the guide rail to be detected, thereby improving detection efficiency and accuracy.

[0064] Optionally, the received data at the second detection point includes at least a height difference from the transmitter to the receiver.

[0065] Optionally, the first detection point and the second detection point are evenly distributed on the guide rail to be detected.

[0066] like Figure 2 As shown, the guide rail installation surface length tested this time is 1300mm. The guide rail length is divided into 5 points as measurement points, and the measurement span is 325mm.

[0067] First, use a level to adjust the machine tool's feet to level the machine tool as a whole, and adjust the transmitter to a level using the precision scale bubble level of the laser calibrator transmitter to ensure that the light emitted by the transmitter remains horizontal. This ensures that the laser emitted by the transmitter is parallel to the ground, and uses this as a reference line to measure each point on the guide rail mounting surface. Place the laser transmitter of the laser calibrator at points A, B, C, D, and E in turn (make sure the precision scale bubble level is level), and place the receiver at the remaining points for measurement.

[0068] Assume that the relative height (i.e. straightness) between point A and point B is h1, the relative height between point B and point C is h2, the relative height between point C and point D is h3, and the relative height between point D and point E is h4.

[0069] When the transmitter is placed at point A, the value displayed by the receiver is the height of points B, C, D, and E relative to point A. When the transmitter is placed at point B, the value displayed by the receiver is: the height of points A, C, D, and E relative to point B. The same applies when the reflector is placed at points C, D, and E.

[0070] The difference between the indicated values ​​of each point can be considered as the height difference of each point, and the difference between each height difference and the straight line fitted by the least squares method is the straightness of each point.

[0071] That is, when the transmitter is placed at point A, the differences between the values ​​displayed by the receiver are h2, h3, and h4; when the transmitter is placed at point B, the differences between the values ​​displayed by the receiver are h1+h2, h3, and h4; when the transmitter is placed at point C, the differences between the values ​​displayed by the receiver are h1, h4, and h1+h2+h3; when the transmitter is placed at point D, the differences between the values ​​displayed by the receiver are h1, h2, and h1+h2+h3+h4; when the transmitter is placed at point E, the differences between the values ​​displayed by the receiver are h1, h2, and h3.

[0072] The terminal device performs data fitting using the least square method using the height difference between two adjacent detection points, i.e., h2, h3, h4 or h1+h2, h3, h4.

[0073] The embodiments of the present application can detect both the measured quantity and the measured quantity having a functional relationship with the measured quantity through the above detection. By directly measuring some measurement values ​​having a functional relationship with the measured quantity and determining the best estimated value of each measured quantity, that is, combined measurement, the least squares method can be used to obtain the best estimated value and the straightness of the guide rail.

[0074] The advantage of using the combined measurement method is that it can greatly reduce the number of measurements and improve the measurement efficiency.

[0075] Some embodiments of the present application improve the accuracy of data detection by evenly arranging detection points on the guide rail.

[0076] It should be noted that each implementable method in this embodiment may be implemented separately, or may be implemented in combination in any combination without conflict, and this application is not limited thereto.
